Abstract
The utility model relates to a detachable pedal, the detachable pedal uses the existing pedal and crank structure; a crank is provided with a hole, an end axle of a pedal is matched with the crank and is provided with a locking device, and the locking device can be movably position clamp type or bead/ trough engagement type. The utility model can reach the purposes of convenient detachability and simple structure, and the utility model has the effects of low cost, good intensity, etc.
Description
The utility model relates to a kind of stretcher of bicycle.
The stretcher of bicycle all is to fixedly install, be stretch-like to the both sides, the foot-operated structure of this tradition often causes the inconvenience of storage and transportation, to disassemble it neither be easy at any time, at folding bicycle, the technical limitation of this part often can not embody little, flexible, the convenient and practical advantage of folding bicycle volume to a greater extent especially.
The purpose of this utility model is at above-mentioned existing problems, proposes a kind of detouchable stretcher.
The utility model utilizes original stretcher and crank, and its crank is provided with a hole, and the end axle of stretcher can screw in the screw thread hole of crank, is provided with gripping mechanism between stretcher end axle and crank.
Described gripping mechanism is made up of a movable clamp and bail, and movable clamp axle is fixed on the end axle of stretcher, and bail is fixed on the crank, cooperates with movable clamp.
Described gripping mechanism also can be formed by stepping on cover, steel ball, dial, spring and locating ring, stepping on cover is fixed in the screw thread hole of crank, step on cover one boss is outwards arranged, boss one end is close to crank, and step on and overlap the shrinkage pool that is provided with more than 2 or 2, stretcher end axle is provided with annular groove, and steps on the shrinkage pool that puts and matches; The dial ring set is in the outer end of stepping on cover, and dial one end is close to the stretcher end by locating ring, and is provided with compression spring between locating ring and dial; The inner ring of the other end of dial is a scalene cone, and steel ball places the shrinkage pool of stepping on cover and pushed down by scalene cone.
Aforesaid detouchable stretcher gripping mechanism, the annular groove that its stretcher end axle is provided with can be substituted by circular groove cover, and circular groove is placed on and steps on that cover is outer, in the dial, and the circular groove cover is provided with shrinkage pool, matches with the circular groove of stepping on the setting that puts.
The utility model employing activity clamp and bail latching device need only rotation activity clamps, will ride outwards to take out to get final product; Also can adopt another kind of locking mode, to extrapolation, the tapered slope on the dial can discharge steel ball the usefulness finger from the shrinkage pool of stepping on cover dial, outwards takes out stretcher thereby take advantage of a situation.
Advantages such as the utility model does not change original structure, and the structure of signing an undertaking is simple, easy to use flexibly, cost is low, safety performance is high, strength stability is good.
Now in conjunction with the accompanying drawings the utility model is further described:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is another structural representations of the utility model;
Accompanying drawing 3 is improvement structural representations of accompanying drawing 2.
As described in accompanying drawing 1, foot-operated 1 end axle 2 interts in the screw thread hole 4 of crank 3, and movable clamp 6 is also rotatable on crank 3 by screw retention, and movable clamp 6 other ends can fasten the end axle.Blocked by end axle 2 when movable clamp 6 goes to the end axle, foot-operated 1 is locked on the crank 3; When stirring movable clamp 6 and break away from, foot-operated 1 extracts out from the hole 4 of crank 3 easily.
As described in accompanying drawing 2, adopt a hollow steel cover as stepping on cover 7, it utilizes the tapped bore of existing crank to be fixed on the crank 3, step on cover 7 and be provided with a boss 15, boss 15 1 ends are close to crank 3, step on the cover 7 and also be provided with two or more shrinkage pools 8, stretcher end axle 2 is provided with annular groove, and correspondence is stepped on the shrinkage pool 8 on the cover 7; Dial 11 is enclosed within to be stepped on the cover 7, an end projection, and the inner ring of projection is provided with scalene cone, so that push down and discharge steel ball 9.Dial 11 other ends are terminated in the end of foot-operated cover by locating ring 13, be provided with compression spring 12 therebetween, compression spring 12 promotes dial 11, scalene cone on the dial 11 is pushed down steel ball 9, the part of steel ball 9 falls within the annular groove of the end axle 2 of stepping on cover 1, be the shape that intermeshes, just be locked on the crank 3 this moment foot-operated 1; During dismounting, to extrapolation, tapered slope just discharges steel ball 9 the usefulness finger from step on cover 7 with dial, takes advantage of a situation and outwards just will ride 1 taking-up from crank 3.
As described in accompanying drawing 3, it is the structural development of accompanying drawing 2, the annular groove 14 usefulness one groove cover 15 that it will be ridden on 1 the end axle 2 substitutes, groove cover 16 is placed in and steps on that cover is 7 outer, in the dial 11, the shrinkage pool on the groove cover 15 with step on cover 7 on the circular groove of setting corresponding, and form a closed geared assembly with the scalene cone of dial 11, foot-operated 1 just is locked on the crank 3, the dismounting action, not only identical with precedent, and also the total except that stepping on cover 7 all can disassemble with stretcher.
